What technology allows routing of voice conversations over the Internet, commonly used in services like Skype?

Voice Over Internet Protocol (VoIP) is the technology that enables the routing of voice conversations over the Internet. It converts analog audio signals into digital data packets, which can be transmitted over IP networks. This technology allows users to make voice calls using the Internet rather than traditional telephone lines, providing flexibility, reduced costs, and additional features like video conferencing and instant messaging.

VoIP works by breaking down voice signals into small data packets, which are then sent across the network using various protocols. This method of communication is not only efficient but also offers significant advantages in terms of scalability and integration with other digital communication services. Services such as Skype leverage VoIP technology to facilitate voice and video calls over the Internet, making it a popular choice for both personal and business communications.

In contrast, Frame Relay is a WAN protocol that is used for connecting devices in a network but does not specifically cater to voice communication. Digital Signal Processing refers to the manipulation of signals in a digital format and can be part of VoIP technology but does not define the technology itself. Integrated Services Digital Network (ISDN) is a circuit-switched telephone network system that carries voice and data, but it is not reliant on the Internet, leading to different kinds of limitations compared to VoIP
